440-4x4

I am wanting to switch to an electric fan rather than a belt driven fan. I dont know much on the subject or have seen much on it, is this a good idea?
Will i have cooling issues? Will the electric fan be able to keep up? What size? all the above.

Any help would be greatly appreciated.
Thanks

I guess it would help to tell you the application and motor.
Its a 440, with mild performance mods nothing extensive, and it will be street driven but also put on a trail or two.

Best this to do is measure your radiator and find out what is the largest fan you can install on it is. From there, you want a fan that flows a high CFM. Install the fan between the radiator and the motor. If you install it in front of the radiator, the air moving across it can cause the blades to flatten out and not be as effective. Don't wire in a switch as most of the time your not watching the temp gauge. Wire in a temp probe and call it done.

My first question is "why do you THINK you want to do this?

Electric fans are not NECESSARILY better for cooling. There's a lot of BS fans out there that are not "better" for several reasons:

They don't include a proper shroud, and leave parts of the radiator "unused."

The don't have good blade designs, and are not efficient within their design

Some simply don't have large enough motors and could never move enough air

Some get installed wrong, as in reversing fans that have curved blades designed to to one way, and therefore pump less air than they should.

I agree with 440, heck,I still run a belt driven clutch fan in my cuda which sees a lot of track time.

If you are not having a problem...........

When four wheeling you are not really going fast enough to help keep the motor cool so with an electric fan, you get the air flow like you would on the highway but at 5MPH.

A fan shroud helps greatly as well, but couple that and a mechanical fan, it sometimes is not enough as I once found out.

Done many conversions. One conversion we have done a lot it the Lincoln Mark VII fan. It flows a crazy amount of air, will easily cool a big block, has two settings so you can select one that matches a good cooling cycle. Done some on 4x4 crawlers and you can run setting one of a manifold water temp sensor and have the high setting on a toggle in the cab.
